To all whom it may concern: I

Be it known that I, DANIEL T. CHAMBERS, of Mansfield, in the county ofRichland and State of Ohio, have invented a new and useful Improvementin Tug-Fasteners for Single- Trees, of which the following is aspecification'.

The object of my invention is to provide a simple, cheap, and easilyoperated device for fastening the traces to a single-tree, and one whichwill securely hold the traces without danger of accidental dislodgment.

It consists of a tilting latch of angular shape hinged upon a horizontalaxis at or near the end of the single-tree, and having one hub adaptedto lie longitudinally with the singletree and the other to projectupwardly at about a right angle thereto, the limb lying longitudinalwith the single-tree being held in such position by the pressure of thetrace, but permitting, when tilted by hand, of the easy dislodgment ofthe trace.

In the drawings, Figure 1 is a verticallongitudinal section through. thesingle-tree and its tug fastener, the latch being shown in the fastenedposition in full lines, while in dotted lines is shown the positionwhich itoccupies in applying the trace. Fig. 2 is a perspective view ofone end of the single-tree with the latch thrown open.

In the figures,A represents the single-tree, made of wood, as usual, andhaving on its upper surface, near the end, a rectangular mortise,forming a seat for the latch.

B is the latch, which, as shown, is made in U shape, and has an eye, a,at one end of its outer end of the mortise.

base to receive a hinge-bolt, b, that passes horizontally through thesingle-tree at the The base 0 of the latch is made on its under sidewith arabbeted edge on each side, that allows the outer edges to restupon the top of the singletree,

while the middle portion descends into the mortise, and this portion ispreferably made thicker at one end than at the other, and also taperedin cross-section, so that it seats in the mortise with a slightlywedging action that prevents rattling.

Now, in applying the trace the latch'is turned up, as shown in dottedlines in Fig. 1 and in full lines in Fig. 2, in which position the limbd lies flat against the outer end of the single-tree. The trace T isthen placed with its slit or eye opposite the end of the single-tree, asin dotted lines, Fig. 1, and is forced over the end of the single-treeand the limb cl of the latch in the direction indicated by the arrow.The latch is then tilted upon its pivot and its other limb orbase dropsto a longitudinal position on the singletree, while the limb (1 standserect. In this position the limb d preventsrthe trace from slipping off,while the pressure of the trace on the base inside its hinge-boltprevents the lat-ch from rising and tilting.

In making use of my invention the inner limb, e, of the U-shaped latchis not absolutely essential, as the increased thickness of thesingle-tree will prevent the trace from passing too far up on thesingle-tree.

Having thus described my invention, what I claim as new is 1. As a newarticle of manufacture, the hinge-latch B, having a base portion, 0,with an eye at one end, and an angularly-projecting limb, d,substantially as and for the purpose described.

2. The combination, with a single tree and a horizontal pivotbolt fixedtherein, of an angular locking-latch consisting of a base and anangularlyprojecting limb hinged at or near its angle to tilt in avertical plane, substantially as andfor the purpose described.

3. The combination, with a single-tree having a recess in its upper sideand a horizontal pivot-bolt fixed therein, 01' the angular locking-latchhinged upon the pivot-bolt and arranged to seat itself in the recess,substantially as and for the purpose described.

4. The combination, with a single-tree having a recess in its upper sideand a horizontal pivot-bolt fixed therein, of an angular lockinglatchwith rabbeted sides hinged upon the pivotbolt, substantially as shownand described.

5. The combination, with a single-tree having a recess in its upper sideand a horizontal pivot-bolt fixed therein, of an angular tilting latchmade wedge shape to bind in its seat, substantially as and for thepurpose described.
